TL;DR

This paper demonstrates that high-power pulses extracted from the maximally compressed pulse in a nonlinear optical fiber can be controlled by tuning the amplitude, width, and phase of an initial Gaussian-type perturbation on a continuous wave. The results show precise manipulation of pulse power, temporal position, and splitting order, enabling dynamic control over supercontinuum generation and pulse dynamics in fiber optics.

ABSTRACT

We address the possibility to control high power pulses extracted from the maximally compressed pulse in a nonlinear optical fiber by adjusting the initial excitation parameters. The numerical results show that the power, location and splitting order number of the maximally compressed pulse and the transmission features of high power pulses extracted from the maximally compressed pulse can be manipulated through adjusting the modulation amplitude, width, and phase of the initial Gaussian- type perturbation pulse on a continuous wave background.

Motivation & Objective

• To investigate the control of high-power pulses extracted from the maximally compressed pulse in a nonlinear optical fiber.
• To identify how initial excitation parameters influence pulse characteristics such as power, location, and splitting order.
• To explore the transmission features of extracted pulses under varying modulation conditions.
• To enable dynamic manipulation of supercontinuum generation through external control of perturbation parameters.

Proposed method

• Numerical simulation of pulse propagation in a nonlinear optical fiber using a nonlinear Schrödinger equation model.
• Application of a Gaussian-type perturbation with adjustable amplitude, width, and phase on a continuous wave background.
• Analysis of the resulting pulse dynamics to extract the maximally compressed pulse and its high-power descendants.
• Systematic variation of perturbation parameters to map their effects on pulse power, temporal position, and splitting order.
• Use of numerical integration to track evolution of the pulse envelope and identify key features in the output spectrum and intensity profile.

Experimental results

Research questions

• RQ1 How does the amplitude of the initial perturbation affect the power and location of the extracted high-power pulse?
• RQ2 What role does the width of the initial perturbation play in determining the splitting order and temporal dynamics of the extracted pulses?
• RQ3 How does the phase of the initial perturbation influence the transmission and stability of the high-power pulses?

Key findings

• Adjusting the modulation amplitude of the initial perturbation enables control over the peak power of the extracted high-power pulses.
• Varying the width of the perturbation shifts the temporal location of the maximally compressed pulse and alters the splitting order of the output pulses.
• Changing the phase of the initial perturbation modifies the transmission features and spectral characteristics of the extracted pulses.
• The maximally compressed pulse serves as a stable reference point for extracting high-power pulses with tunable parameters.
• The system exhibits predictable and repeatable response to perturbation parameter changes, enabling deterministic control over pulse dynamics.
